It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
A terminal device in this application may refer to a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. The wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a Terminal Device, a User Agent (User Agent), a User Device (User Device), or a User Equipment (User Equipment), which is not limited in this application.
Fig. 1 is a flowchart illustrating a cell reselection processing method according to an embodiment of the present invention. In this embodiment, the execution main body of the method may be a terminal device, and the terminal device may specifically be a mobile phone, a tablet computer, a wearable device, and the like, which is not limited herein. As shown in fig. 1, includes:
and S101, starting a first timer and a counter according to a reselection instruction.
The reselection instruction refers to a cell reselection instruction, and the cell reselection refers to a process of selecting a cell, in which the states of signal strength, quality and the like in the cell of the neighboring cell meet a preset cell screening condition, by detecting the signal quality of the neighboring cell of the different system and the current cell when the terminal device detects that the states of signal strength, quality and the like of the cell in which the terminal device is located reach a preset threshold value. Further, the reselection instruction refers to a cell reselection instruction corresponding to the cell reselection procedure.
When the terminal device serves as an execution main body, after a reselection instruction is received, the terminal device starts a first timer and a counter, wherein the first timer and the counter are started simultaneously, the first timer is used for timing, and the counter is used for counting so as to detect reselection time of the terminal device during cell reselection. Before starting the timer and the counter, it should be determined whether the values of the first timer and the counter are both zero, and if not, the values of the first timer and the counter should be set to zero, and then the timing and the counting are respectively started.
S102, when the timing duration of the first timer does not reach a first preset threshold and the count value of the counter reaches a second preset threshold, determining a first network mode according to the current network state.
The first preset threshold refers to a timing threshold of the first timer, and the second preset threshold refers to a counting threshold of the counter, where the setting of the first preset threshold and the second preset threshold may be a default threshold set according to experience of reselection, or may be a threshold set by itself according to an actual application situation, which is not limited in the present application, and one counting of the counter refers to a process in which the terminal device goes from the a network mode to the B network mode, and then goes back to the a network mode from the B network mode.
And detecting the timing duration of the first timer and the count value of the counter according to the setting of a first preset threshold and a second preset threshold, and determining a first network mode according to the current network quality, state and the like when detecting that the timing duration of the first timer does not reach the first preset threshold and the count value of the counter reaches the second preset threshold. The current network state is the network state of the terminal device when the current network state detects that the timing duration of the first timer does not reach the first preset threshold and the count value of the counter reaches the second preset threshold.
The network mode in the present application may include: a Second Generation mobile communication (2G) network mode, a Third Generation mobile communication (3G) network mode, a Fourth Generation mobile communication (4G) network mode, a Fifth Generation mobile communication (5G) network mode, and the like, and it is needless to say that which mode is to be specifically switched to is determined according to the current network state detected by the terminal device, and the present application does not limit this.
For example, when the terminal device is located in a certain specific area, the network mode when receiving the reselection instruction is the 4G network mode, and when the terminal device detects that the current 4G network signal strength, quality, and the like reach a preset threshold of a ping-pong effect, the terminal device generates the ping-pong effect in the specific area, and needs to perform reselection of the network mode, therefore, the terminal device will receive the reselection instruction, start the first timer T _ ping and the counter N _ ping according to the reselection instruction, further start timing by the first timer T _ ping, and start counting by the counter N _ ping.
Here, taking the value of the first preset threshold as 1 minute and the value of the second preset threshold as 5 times as an example for explanation, when the terminal device detects that the timing of the first timer T _ pingping does not reach 1 minute and the count of the counter N _ pingping exceeds 5 times, the terminal device detects the network state of the current specific area, and according to the current network state, the terminal device preferentially determines to switch the current network mode from the 4G network mode to the 3G network mode with a lower level, and if the current network state does not satisfy the 3G network signal, then determines to switch the current network mode from the 4G network mode to the 2G network mode with a lower level.
That is, according to the network mode of the terminal device when receiving the reselection instruction, when detecting that the timing duration of the first timer does not reach the first preset threshold and the count value of the counter reaches the second preset threshold, according to the network state, the terminal device determines to switch to the network mode lower than the current network mode according to the level of the network mode. Wherein, the network mode levels of 5G, 4G, 3G and 2G are reduced in sequence. For example, when the current network mode is a 5G network and a reselection instruction is received, the terminal device may switch to any one of the 4G, 3G, and 2G network modes, and the specific switching of which network mode is switched may be determined according to a network state. For example, if the current network state allows the 4G network, the current network state is preferentially switched to the 4G network state, otherwise, it is determined whether the current network state can be switched to the 3G network mode, if the current network state does not allow the 3G network mode, the current network state is switched to the 2G network mode, and so on.
S103, switching the current network mode to a first network mode.
After determining the first network mode according to the network state, the terminal device may switch the current network mode to the first network mode, where the first network mode is a network mode switched after receiving the reselection instruction.
That is, switching is performed according to the first network mode determined by the terminal device in step S102, for example, if the current network mode of the terminal device is the 4G network mode and the determined first network mode is the 3G network mode, the terminal device will switch from the 4G network mode to the 3G network mode.
According to the cell reselection processing method provided by the embodiment of the application, the timing duration of the first timer and the count value of the counter are detected, when the detection timing duration does not reach the first preset threshold value and the count value reaches the second preset threshold value, the first network mode is determined according to the current network state, so that the current network mode is switched to the first network mode, the terminal device is switched and kept working in the first network mode when a certain condition is met, the terminal device is prevented from continuously performing measurement and reselection evaluation among systems, the overhead of the terminal device can be effectively reduced, and the power consumption of the terminal device is further reduced.
Fig. 2 is a flowchart illustrating another cell reselection processing method according to an embodiment of the present invention. Since the terminal device operates in the first network mode when the current network mode is switched to the first network mode, in order to enable the terminal device to operate in a higher-level network mode within a certain period of time, as shown in fig. 2, optionally, after the current network mode is switched to the first network mode, the method further includes:
s201, starting a second timer.
The second timer is used for calculating the operation duration of the terminal device working in the first network mode after being switched to the first network mode, where it should be noted that before the second timer is started, it may also be determined whether the value of the second timer is zero, and if not, the second timer value is set to zero and then timing is started. The second timer is exemplified as a T _ MODE timer in the present application.
S202, when detecting that the timing duration of the second timer reaches a third preset threshold value, switching the current network mode from the first network mode to the second network mode according to the current network state.
The third preset threshold refers to a timing threshold of the second timer, and the third preset threshold may be a default threshold set according to experience of reselection, or may be a threshold set by itself according to an actual application situation, which is not limited in this application. The third preset threshold value is taken as 30 seconds for explanation in the present application.
When the terminal device detects that the timing duration of the second timer reaches a third preset threshold, the current network mode is switched from the first network mode to the second network mode according to the current network state, so that the terminal device operates in the second network mode, that is, through the setting of the second timer, when the timing duration of the second timer reaches the third preset threshold, the terminal device can switch the network mode in time according to the current network state, for example, if the signal condition of the network mode at a higher level reaches a preset requirement, the terminal device is switched to other network modes at a higher level than the current network mode. When the ping-pong effect does not occur any more, the terminal equipment can work in a higher network mode, and a user can have better user experience.
Such as: after the T _ MODE timer is started, the T _ MODE timer starts to time, at this time, the network MODE of the terminal device is the 3G network MODE, when the time duration of the T _ MODE timer reaches 30 seconds, the terminal device switches the current 3G network MODE into the 5G network MODE according to the current network state and when the current network state is allowed to be switched to 5G, and then works in the 5G network MODE, otherwise, when the current network state is allowed to be switched to 4G, the mobile terminal switches the current 3G network MODE into the 4G network MODE, and then works in the 4G network MODE, and compared with the working in the 3G network MODE, the mobile terminal works in the 5G or 4G network MODE, and better user experience is obtained.
Fig. 3 is a flowchart illustrating a processing method for cell reselection according to another embodiment of the present invention. Optionally, as shown in fig. 3, after starting the second timer, the method further includes:
s301, acquiring current first position information.
After the T _ MODE timer is started, that is, when the timing duration of the T _ MODE timer does not reach the third preset threshold, the current first location information is obtained. The current first location information refers to location information when the terminal device receives a reselection instruction, and the location information may be obtained based on a Global Positioning System (GPS) of the terminal device, which is not limited in this application.
S302, writing the first position information into a preset position list.
The preset position list is used for storing the position information of the terminal equipment when the timing duration of the second timer does not reach a third preset threshold after the second timer is started, namely the position information of the terminal equipment when the ping-pong effect occurs. In the present application, the preset location list is referred to as ping _ list as an example for explanation.
Fig. 4 is a flowchart illustrating another cell reselection processing method according to an embodiment of the present invention. According to the position information recorded in the preset position list, when the terminal equipment receives the reselection instruction again, the terminal equipment can switch the network mode in time according to the preset position list. Optionally, as shown in fig. 4, after the detecting that the timing duration of the second timer reaches a third preset threshold, the switching the current network mode from the first network mode to the second network mode according to the current network state further includes:
s401, if a reselection instruction is received, acquiring current second position information.
The reselection instruction is the same as the above, and is also referred to as a cell reselection instruction. And when the terminal receives the reselection instruction again, acquiring the position information of the terminal equipment.
S402, judging whether the preset position list comprises second position information or not.
Whether the second position information is included in the preset position list is judged according to the existing preset position list, and the specific judgment mode can be judged by adopting a key information retrieval mode and the like, which is not limited in the application.
And S403, if the preset position list comprises the second position information, determining a third network mode according to the current network state.
If the current preset position list comprises second position information, namely the second position information has a ping-pong effect before and receives a reselection instruction. At this time, the network mode to be switched may be determined directly according to the second location information and the current network state existing in the preset location list, so as to avoid the terminal device executing the method shown in fig. 1 to complete the switching when the terminal device is at the second location, save the determination process, and effectively reduce the overhead of the terminal device in the process.
In addition, if the preset location list does not include the second location information, referring to the method steps shown in fig. 1, the first timer and the counter are started. The present application takes configuring a first timer as a first preset threshold and a counter as a second preset threshold as an example for explanation. And after configuring the corresponding timer and the counter, determining a third network mode according to the network state of the current second position.
S404, switching the current network mode from the second network mode to a third network mode.
And the third network mode is a network mode which determines to switch when the terminal equipment judges that the obtained second position information comprises the current preset position list when the terminal equipment receives the reselection instruction. Because the network state is not always constant and is influenced by other factors, the network states of the terminal devices at different moments may be the same or different.
Optionally, according to different actual network states, the relationship among the first network mode, the second network mode, and the third network mode is: the second network mode is higher than the first network mode and the third network mode, and the first network mode and the third network mode may be the same or different, which is not limited in this application. Among the network mode levels, the network mode levels of 5G, 4G, 3G, and 2G are sequentially lowered.
For example, the current network mode in which the terminal device is located is a 4G network, and when receiving the reselection instruction, the terminal device switches the current network mode from the 4G network to a first network mode, namely a 3G network, with a lower level according to the steps S101, S102, and S103; at this time, the terminal device is in the 3G network, and according to the steps S201 and S202, the current 3G network mode is switched to the second network mode 4G network with a higher level; at this time, the terminal device is in the 4G network, and switches the current 4G network mode to the third network mode 2G network with a lower level according to the steps S401, S402, S403 and S404. At this time, the second network mode (4G) is higher in level than the first network mode (3G) and the third network mode (2G), and the first network mode (3G) is different from the third network mode (2G).
The process of switching the terminal device from the second network mode to the third network mode is as follows. For example, when the terminal is in the second network mode 3G and receives the reselection instruction at this time, the terminal device obtains that the second location information where the terminal device is located is a, and determines whether the second location information a is included in the preset location list pingping _ list, and when the second location information a is included in the preset location list pingping _ list, the terminal device determines the network mode to be switched according to the current network state of the terminal device, for example, according to the current network state, the network mode determined by the terminal is the third network mode 2G, and the terminal switches the second network mode 3G to the third network mode 2G.
Optionally, starting a first timer and a counter according to the reselection instruction includes: and when the current position information is not contained in the preset position list, starting a first timer and a counter according to the reselection instruction.
If the preset location list does not contain the current location information of the terminal device according to the reselection instruction, restarting the first timer and the counter according to the reselection instruction, wherein the specific process may refer to step S101, and this application is not described herein again.
Optionally, when it is detected that the time duration of the second timer reaches a third preset threshold, after the current network mode is switched from the first network mode to the second network mode according to the current network state, the method further includes: and if the current position information is the first position information and the reselection instruction is not received after the preset time length is exceeded, deleting the first position information from the preset position list.
The current position is recorded in a preset position list, whether the ping-pong effect still occurs in the current position information of the terminal equipment is judged by setting a preset time length, for example, whether a reselection instruction is received is judged, if the reselection instruction is not received, it is determined that the ping-pong effect does not occur any more, the current position information is deleted from the preset position list, and the position information in the preset position list is updated in time.
For example, it is known that the preset location list includes location information B, the time when the location information B is recorded in the preset list is t, the preset duration is 5 hours (hour, h), and when the terminal device does not receive a reselection instruction at the location information B within the time of t-t +5h, the location information B is deleted from the preset location list.
Fig. 5 is a flowchart illustrating another cell reselection processing method according to an embodiment of the present invention. Optionally, as shown in fig. 5, the method includes:
s501, acquiring a reselection instruction.
And S502, after receiving the reselection instruction, acquiring the current position information.
S503, judging whether the preset position list contains the current position information.
If so, perform S504, otherwise perform S506.
And S504, if the preset position list comprises the current position information, determining a third network mode according to the current network state.
And S505, switching the current network mode to a third network mode.
And according to the third network mode determined in the step S504, the terminal equipment switches the current network mode into the third network mode.
And S506, if the current position information is not contained in the preset position list, starting a first timer and a counter according to the reselection instruction.
After the first timer and the counter are started, the first timer starts to time, and the counter starts to count.

And according to the first network mode determined in the step S507, the terminal device switches the current network mode to the first network mode.
And S509, starting a second timer, and writing the current position information into a preset position list.
And S510, waiting for the timing duration of the second timer to reach a third preset threshold value.

If so, go to step S512, otherwise continue to wait.
And S512, when the timing duration of the second timer reaches a third preset threshold value, switching the current network mode from the first network mode to the second network mode according to the current network state.
